I am searching for experimental spin-orbit coupling constants, particularly for main group elements and Cr(0) to calculate correlation consistent Composite Approach (ccCA) energetics. This method requires the application of experimental spin-orbit coupling constants (Table 1, ). I have found and read several other papers that use experimental spin orbit coupling constants, but none have a corresponding reference. I have also searched other places like NIST, etc. but have not found anything. Where can I find these experimental values for spin-orbit coupling constants?
